BRICKMAKING-MACI-IINE.

To all whom it may concern:

Be it known that I, EDMUND GURNEY, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Bricklnaking- Machines, of which the following is a specification.

. My previous application for patent filed January 16, 1912, Serial Number 671,439, discloses certain improvements in clay working machinery, embodying particularly a special construction of brick cutting table or machine having automatically operable means associated therewith for supporting brick after they have been cut and for transferring the spread brick to a conveyer.

The present invention appertains to the means above referred to and includes primarily differently operating means for effecting the transfer of the cut spread brick from the cutting table to the conveyer, which last mentioned means is especially adapted for use in connection with certain types of cutting machines or tables, and may be advantageously used in substitution for the equivalent mechanism set forth in my previous application. In my previous application, I also describe the use of a stop which is automatically actuated in the movement of the carriage on the cutting table, where by to engage with the cut brick at a predetermined time to shift said brick from a spreading pallet to a portable pallet or to a conveyer.

The present invention embodies certain operating means for said stop to restore the same to its normal position out of the path of movement of the brick at a predetermined time in the operation of the machine.

For a full understanding of the present invention, reference is to be had to the following description and to the accompanying drawings, in which- Figure 1 is a side elevation of a brick cutting machine or table, showing the invention applied thereto. Fig. 2 is a view showing more clearly the conveyer as arranged in relation to the portable pallet and the Specification of Letters Patent.

bracket means for supporting the depressible delivery arms of the carriage. Fig. 3 is a side view of the parts shown in Fig. 2 and other adjacent parts, the carriage being broken away. Fig. l is a detail front elevation bringing out more clearly the standard supporting the bell crank lever which is operable by the main lever and connected for actuation of the stop.

Throughout the following detail description and on the several figures of the drawings, similar parts are referred to by like reference characters.

As shown most clearly in the drawings, the cutting table or machine in connection with which the present improvements are used is of a conventional type, embodying the frame 1, the main operating lever 2, the carriage 3 and the stop plate 4. The operating lever 2 is mounted upon a shaft 5 in the customary manner, arms of said shaft being connected by links 6 with the carriage 3 so that the carriage may be reciprocated upon the frame 1 by means of the back and forth movement of the lever 2. The cutting wires 7 are carried back and forth in the cutting operation bythe carriage 3, being attached to the carriage in the customary manner.

As in my application previously referred to, I mount upon the carriage 3 a spreader pallet 8 composed of a plurality of units adapted to be spread automatically as the carriage 3 is moved to the right in Fig. l and to be closed together as the carriage is moved to the left, referring to the same figure of the drawings. At one side of the pallet 8 are mounted a plurality of transfer rolls 9, said rolls extending transversely of the frame of the table, parallel with the pallet 8 and between said pallet and delivery arms 10 Which are carried by the extreme ends of the sides of the carriage opposite the end of the machine at which the cutting mechanism is located.

The delivery arms 10 aforesaid are hingedly or pivotally connected with the carriage at 11 and springs 12 connect adjacent end portions of the carriage and said arms for a-purpose to be hereinafter described.

Brackets 13 secured to the adjacent end of the frame 1 of the machine are formed with laterally projecting supporting arms 14 having rollers 15 journaled at their outer extremities, said brackets being also formed with the vertical arms 16 having the antifriction rollers 17 at their upper ends. At the outer ends of the delivery arms 10, each arm has a combined stop and anti-friction roller 18 mounted thereon and projecting slightly above the surface of the arm. A

portable pallet 19 is shown in positionon, the delivery arms 10, in Fig. 3 of the drawings, and bricks 20 are illustrated as carried on the pallet.

Standards 21 are detachably mounted on the frame 1 near the delivery end of the frame and these standards carry the stop 22 which is vertically movable in guide slots 23 on the standards. Projections 2 1 at the ends of the stop 22 are engageable by catches 25. pivoted to the standards 21 and the catches 25 have arms which are in the path of movement of the horizontal arms 26 of the carriage 3, said arms 26 having the upper ends of the cutting wires attached thereto. Connected with the stop 22, preferably at its middle portion, is a wire, rope, or other flexible connection 27 passing over a pulley 28 above the machine and extending to the long arm of the crank lever 29. The

lever 29 is pivoted to the upper end of a standard 30detachably secured to the floor or base upon which the machine is arranged and located at one side of the lever 2 so that,

in the movement of the lever 2, a lug 31 of a detachable collar 32 on the lever will be adapted to strike the short vertical arm of the lever 29 and tilt the latter in the operation of the machine.

The operation of the machine in detail will now be described: The bar or stick of clay which is to be cut up to form the bricks is fed upon the cutting table or machine in the customary way until it strikes the stop ping plate 1. The operator of the machine then swings the lever 2 to the left, as shown in Fig. 1, thereby moving the carriage 3 until the stick or bar of clay is cut into separate bricks by means of the cutting wires 7. During the cutting operation, the movement of the carriage 3 slides the pallet 8 under the bricks and the operator will then move the lever 2 to the right into the dotted line position in Fig. 1, thereby carrying the bricks bodily on the pallet toward the delivery end of the machine. The bricks in the above operation are spread by means of cooperating with the various units of the pallet 8 and fully set forth in my previous application for patent. \Vhen the car riage 3 reaches the limit of its delivery movement, as shown in dotted lines in Fig. 1, the bricks will be supported by the pal- I will sweep the bricks in spread condition,

from the pallet 8 over the rolls 9 onto the portable pallet 19, shown in Fig. 3. "At this stage of the operation, the parts appear as in full lines in Fig. 3 and the next right hand movement of the lever 2 initially causes thelug 31 thereon to strike the vertical arm of the lever 29, thereby exerting a pull upon the connection 27, raising the stop 22 until the latter is supported again by the catches 25. Subsequent movement of the lever- 2 and carriage 3in the right hand direction will move the delivery arms 10 into the dotted line position shown in F 3, said arms 10 sliding over the rollers 17 and 15. By reason of the weight of the bricks on the pallet 19, the arms 10 will be depressed into inclined positions and the lowering movement of the arms permits the pallet now supported thereby to be engaged by the conveyer 33 'and carried off to the drying means. Just as soon as the pallet 19 hasbeen engaged and removed from the arms 10, by the conveyer 33, the springs 12 act to lift the arms 10 so that a fresh empty pallet 19 may be placed on the arms and not engaged by the conveyer even though the lever'2 is at its right hand limit of movement. In other words, the weight of the fresh pallet 19 alone would not be sufficient to depress the arms 10. The rollers 18 on the delivery arms 10 perform a peculiar function in that as the bricks 20 are shifted from the-pallet 8. over the rolls 9 to the pallet 19, there is a tendency for the pallet 19 tobeshoved off of the supporting arms 10. The outeredge of the pallet 19, however, rests "against the rollers 18, and the latter constitute stops preventing the movement referred to. However, inthe deof the stop 22 at the proper time in theoperation of the machine. It is contemplated furthermore tomake further modifications in the details of construction as hereinbefore presented and consistent with the broader spirit of the invention and scope. of the claims hereto appended.
